46. Amblyomma gemma Dönitz, 1909 .

An Afrotropical species whose adults are usually found on Artiodactyla : Bovidae , but all parasitic stages have been recovered from these hosts. Adults and nymphs have been collected from Artiodactyla : Camelidae and Suidae , and Perissodactyla : Equidae ; adults alone have been recovered from Mammalia (several orders), Struthioniformes : Struthionidae , and Testudines : Testudinidae ; and immature stages have been collected from Lagomorpha : Leporidae , Rodentia : Sciuridae , and Aves (several orders). Amblyomma gemma is a very rare parasite of humans.

Note: see Amblyomma eburneum for a discussion of difficulties concerning that species’ diagnosis and its confusion with Amblyomma gemma . Voltzit and Keirans (2003) state that the hypostomal dental formula of the Amblyomma gemma nymph is 2/2, but the corresponding figure shows 3/3 dentition.
